What does Chapter 7 say about Sai Baba's views on caste and social purity?

Chapter 7 portrays Sai Baba as someone who completely transcended caste distinctions and notions of ritual purity. It states that for one who has no ego regarding the body, distinctions like Hindu or Muslim, or Shudra or outcaste, did not matter in the slightest. This is powerfully illustrated by the fact that the most elite Brahmins and keepers of the sacred fire (Agnihotris) would abandon their pride in ritual purity and prostrate before him. Furthermore, his mind felt no disgust even if a dog were to put its mouth in the food, showing his profound detachment from conventional social hierarchies and his equal vision for all beings.
